Hey I am surprised that you haven't got any compilation error on your code. You can do like this var a=Mail A-mail.a@some.com;Mail B-mail.b@some.com; var ids = a.Split( new string [] {;} StringSplitOptions.RemoveEmptyEntries); //Now extract all your ids for ( int x =0; x { var id = ids[x].SubString(ids[x].IndexOf( - )+1); // Now do your stuff with id }

Hi Ayesha Please try this code public static void splitexp() { var a = Mail A-mail.a@some.com;Mail B-mail.b@some.com; ; string [] result = a.Split( new Char[] { '-'  ';' } StringSplitOptions.RemoveEmptyEntries); for ( int i = 1; i { Console.WriteLine(result[i]); } }

Hey First split your string with ; (semicolon) and then use your substring logic

Amit is currect .But a simple change public static void stringarray_func() { var a= Mail A-mail.a@some.com;Mail B-mail.b@some.com; ; string [] ids = a.Split( new string [] { ; } StringSplitOptions.RemoveEmptyEntries); //Now extract all your ids for ( int x =0; x { var id = ids[x].Substring(ids[x].IndexOf( - )+1); Console.WriteLine(id); // Now do your stuff with id } Console.ReadKey(); }

Hi Amit Like that only iam doing a.split(;) a.substring(a.indexOf(-) + 1 a.indexOf(;)); then it's giving only first one -mail.a@some.com
